Study suggests 76% of Brazilian coronavirus strains had origins in Europe

A new study shedding light on the epidemic transmission and evolutionary trajectories of the coronavirus in Brazil has shown that current interventions remain insufficient to contain the virus.

The research, published in Science a week ago, came amid the country registering the world's second highest number of confirmed cases with more than 2.6 million people getting infected.

Scientists found 75 percent of the strains in Brazil had their origins in three groups that were introduced from Europe in late February and early March, indicating transmission was already established in Brazil by early March.

Most of these estimated introductions were directed to internationally well-connected states such as Sao Paulo (36% of all imports), Minas Gerais (24%), and Ceara (10%), said the study.
